REPORTS ON EXPERIMENTAL WORK 



IN CONNECTION WITH 



By H. J. FRANKLIN and F. W. MORSE 



This bulletin contains a full report on the work at the cran- 

 berry substation at Wareham for the year 1913, by H. J. Franklin, 

 and a report on the results of the study of the water of the arti- 

 ficial cranberry bogs in Amherst, by F, W. Morse. 



Dr. Franklin's report presents conclusions on many important 

 points, among which some of the more prominent are frost pro- 

 tection, prevention of fungous diseases, effects of fertilizers, de- 

 struction of injurious insects with especial reference to flowed-bog 

 fire worm and the fruit worm, insect parasites, weed destruction 

 and resanding. 



Professor Morse presents the results of numerous analyses of 

 bog water, and shows that up to the present time there seems to 

 be no direct relation between varying applications of fertilizers 

 and the composition of the drainage water. His work shows a 

 direct relation between free circulation of water and drainage and 

 vine growth. 



Requests for bulletins should be addressed to the 



Agricultural Experiment Station,
